I'm looking for any information about flying into California with my pistol.  I have an upcoming trip where I will be flying into San Diego, staying for a few days, then driving to Vegas, and flying home out of Vegas.  I don't plan to carry in California, i only have Hawaii and Arizona carry licenses.  My pistol is on the California DOJ handgun roster (Springfield Armory XD9801).  It would remain locked up (per TSA requirements) at my Air B&B during my time in CA.  I should be ok right?  Am I forgetting anything, or have I overlooked some regulation I dont know about?   Any knowledge or advice is welcome.
Thanksl

Funny story.  Not sure if true since its a "person heard it from a person kind of story."  But someone apparently tried to register a couple of completed 80% pistol receivers on the Big Island and the police told them "they dont have serial numbers so you dont have to register them"  If true, I wonder how many are out there floating around because the police dont think they need to be registered?  true ghosts on the Island of huaka'i pō?   

Given how they do not know the law on who needs a mental health clearance assessment, I would not be surprised if this was true.

The above is true, I’ve heard a similar version from a reliable source. When the police said "they dont have serial numbers so you dont have to register them", what they really meant is they have no procedure in place to register unserialized lowers.  At least they didn’t confiscate the lowers.

they filed a motion to extend time

So they're asking for 45 more days, until 9/15? If that motion gets granted, what does that mean exactly?
The Hawaii court has to rehear the case by 9/15? Sorry, not trying to be ignorant, but legal jargon and procedure confuses me. 
Lol, trying to not get my hopes up but at the same time I'd like to know what's happening, what's ahead, timeframes ( hopefully not another 6 years), etc.

To the folks living on the big island especially in or around Hilo, has anyone ever been to Selectfire? What’s it like compared to the other gun shops in the Hilo area? It’s located at such an odd place and I just never hear anything about the store.

Selectfire used to be in the Ironworks building, he works out of his home now though. The majority of his stock is rifles, and he does custom builds (AR,AK) but he also has pistols as well. Nice guy, easy to work with. If you have instagram search selectfiregunsandammo. All his contact info is there
